Especially in multi-functional vehicles, the adjustability and space utilization of seats have become important factors affecting user experience.

[0003] Currently, most car seats have a certain degree of folding function on the backrest to expand the trunk space or facilitate the entry and exit of rear passengers.

[0004] In conclusion, although some existing technical solutions have solved the problem of seat folding, there is still considerable room for improvement in terms of folding convenience and user experience optimization. Summary of the Invention

[0005] The purpose of this utility model is to address the aforementioned problems existing in the prior art by proposing a foldable car seat, comprising:

[0006] A base and a backrest, the base and the backrest being rotatably connected, the base being provided with a locking groove and the backrest being provided with a locking hole;

[0007] The folding assembly includes the rotating member and the locking member. The two ends of the rotating member are hinged to the backrest, and the middle part is rotatably inserted through the base. The locking member is slidably disposed in the locking groove and can extend into or out of the locking hole to restrict or release the rotation of the backrest.

[0008] The aforementioned foldable car seat also includes an adjustment handle, which is slidably connected to the base. The adjustment handle is provided with a first guide groove, which is inclined relative to the sliding direction of the locking member. The locking member is provided with a first guide block, which is accommodated in the first guide groove.

[0009] The aforementioned foldable car seat also includes a first elastic element, one end of which abuts against the adjustment handle, and the other end of which abuts against the base.

[0010] In the aforementioned foldable car seat, both the adjustment handle and the base are provided with positioning components, and the two ends of the first elastic member are respectively connected to the positioning components on the adjustment handle and the base.

[0011] In one of the aforementioned foldable car seats, the number of locking holes is at least two.

[0012] In one of the aforementioned foldable car seats, the base is also provided with a mounting slot, which can be used to add items such as water cups.

[0013] The aforementioned foldable car seat also includes a headrest, and the backrest is provided with a lifting groove. The two sides of the headrest are accommodated in the lifting groove. The headrest also includes a fixing tooth, which is slidably connected to the headrest, and one end of the fixing tooth can be engaged with the lifting groove.

[0014] In the aforementioned foldable car seat, the headrest further includes a lifting handle, which is vertically and flexibly connected to the headrest. The lifting handle is provided with a second guide groove, which is inclined relative to the sliding direction of the fixing tooth. The fixing tooth is provided with a second guide block, which is accommodated in the second guide groove.

When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the protection scope claimed by this utility model.

[0032] The specific embodiments described herein are merely illustrative examples of this utility model patent. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or adopt similar methods to replace them, but without departing from the patent of this utility model or exceeding the scope defined by the appended claims.

[0033] like Figures 1-4 As shown, a foldable car seat includes: a base 1, a backrest 2, and a folding assembly 3.

[0034] The base 1 and the backrest 2 are rotatably connected. The base 1 is provided with a locking groove 11 and the backrest 2 is provided with a locking hole 21.

[0035] The folding assembly 3 includes a rotating member 31 and a locking member 32. The two ends of the rotating member 31 are hinged to the backrest 2, and the middle part is rotatably inserted through the base 1. The locking member 32 is slidably disposed in the locking groove 11 and can extend into or out of the locking hole 21 to restrict or release the rotation of the backrest 2.

[0036] Specifically, when the locking member 32 exits from the locking hole 21 and passes through the locking groove 11, the base 1 and the backrest 2 are rotatably connected through the rotating member 31. At this time, the locking member 32 no longer constrains the relative position of the two, so that the backrest 2 can rotate freely relative to the base 1. When it is necessary to fix the position of the backrest 2, the locking member 32 is inserted back into the locking hole 21. The locking member 32 and the locking hole 21 cooperate to form a limiting structure, which restricts the relative rotation between the base 1 and the backrest 2, thereby keeping the backrest 2 stably at the required angle.

[0037] In this embodiment, the backrest 2 and the base 1 can be switched between movable and fixed states by extending and retracting the locking member 32. In the folded state, the backrest 2 can be tightly folded against the base 1, which significantly reduces the overall space occupied and facilitates transportation, storage or use in a small space. In the unfolded state, the reliable locking of the locking member 32 can ensure the stability and safety of the seat structure and provide stable and comfortable support for the user.

[0038] like Figures 1-4 As shown, based on the above embodiment, it also includes an adjustment handle 4, which is slidably connected to the base 1. The adjustment handle 4 is provided with a first guide groove 41, which is inclined relative to the sliding direction of the locking member 32. The locking member 32 is provided with a first guide block 321, which is accommodated in the first guide groove 41.

[0039] Specifically, since the first guide groove 41 on the adjustment handle 4 is inclined relative to the sliding direction of the locking member 32 and the first guide block 321 on the locking member 32 is accommodated in the first guide groove 41, the locking member 32 can be moved when the adjustment handle 4 is pulled.

[0040] In this embodiment, by converting the axial sliding of the locking member 32 into the movement direction of the adjusting handle 4, the user only needs to apply a simple lifting action to smoothly complete the unlocking or locking operation of the locking member 32 through the mechanical mechanism between the first guide groove 41 and the first guide block 321, avoiding the inconvenience and space limitations caused by directly manually moving the locking member 32.

[0041] like Figures 1-4 As shown, based on the above embodiment, a first elastic element (not shown in the figure) is also included. One end of the first elastic element abuts against the adjustment handle 4, and the other end of the first elastic element abuts against the base 1.

[0042] Specifically, when the adjustment handle 4 is pulled, the first elastic element is compressed and the locking element 32 disengages from the locking hole 21. At this time, the base 1 can be rotated while the adjustment handle 4 is released. The adjustment handle 4 is reset under the action of the first elastic element until the locking element 32 is aligned with the locking hole 21 during the rotation of the base 1. Then the adjustment handle 4 can be completely reset under the action of the first elastic element.

[0043] In this embodiment, after the adjustment handle 4 is pulled to unlock, the user can freely adjust the relative angle between the backrest 2 and the base 1. When the backrest 2 is adjusted to the required angle, under the action of the first elastic element, the locking action can be automatically completed without manually pushing the adjustment handle 4 back or applying additional operations. This not only optimizes the user experience, but also effectively avoids safety hazards caused by negligence in not completing the locking.

[0044] like Figures 1-4 As shown, based on the above embodiment, both the adjusting handle 4 and the base 1 are provided with positioning members 12, and the two ends of the first elastic member are respectively connected to the adjusting handle 4 and the positioning members 12 on the base 1.

[0045] Specifically, the first elastic element is a spring, and the positioning element 12 on the adjusting handle 4 and the positioning element 12 on the base 1 extend into both ends of the spring to prevent it from bending, twisting or shifting laterally during compression or elongation.

[0046] In this embodiment, the positioning member 12 ensures that the central axis of the first elastic member is consistent with the movement direction of the adjusting handle 4, preventing lateral bending during compression or elongation while ensuring that the elastic force is transmitted evenly and reducing off-center wear.

[0047] like Figures 1-4 As shown, based on the above embodiment, the number of locking holes 21 is at least two.

[0048] In this embodiment, the number of locking holes 21 is at least two, and multiple locking holes 21 are distributed at intervals along the rotation arc direction of the base 1 or the backrest 2 to form a set of optional positioning point arrays, which can realize the multi-level adjustable function of the seat backrest 2.

[0049] like Figures 1-4 As shown, based on the above embodiment, the base 1 is also provided with an assembly slot 13, which can be used to add items such as water cups.

[0050] Specifically, the assembly slot 13 adopts an embedded structure, which can meet the personalized needs of users in different usage scenarios by adding additional accessories such as water cups.

[0051] like Figures 1-4 As shown, based on the above embodiment, it also includes a backrest 5, and the backrest 2 is also provided with a lifting groove 22. The two sides of the backrest 5 are accommodated in the lifting groove 22. The backrest 5 also includes a fixing tooth 51, which is slidably connected to the backrest 5, and one end of the fixing tooth 51 can be engaged with the lifting groove 22.

[0052] Specifically, the backrest 2 is provided with a vertically extending lifting groove 22. The lifting groove 22 is a strip-shaped slide structure symmetrically distributed on both sides of the backrest 2. The left and right sides of the pillow 5 are respectively embedded and accommodated in the lifting groove 22, thereby realizing the sliding installation of the pillow 5 on the backrest 2. The pillow 5 is also equipped with a fixing tooth 51 that can cooperate with the lifting groove 22. When the pillow 5 is adjusted to the required height, the fixing tooth 51 can engage and lock with the buckle hole in the lifting groove 22, thereby realizing the stable fixation of the pillow 5.

[0053] In this embodiment, the fixed teeth 51 inside the backrest 5 engage with the lifting groove 22, allowing the backrest 5 to be adjusted in height at will, fully adapting to the needs of different heights, sitting habits, or usage scenarios for back support, thus significantly improving the user experience.

[0054] like Figures 1-4 As shown, based on the above embodiment, the pillow 5 further includes a lifting handle 6, which is vertically connected to the pillow 5. The lifting handle 6 is provided with a second guide groove 61, which is inclined relative to the sliding direction of the fixed tooth 51. The fixed tooth 51 is provided with a second guide block 511, which is accommodated in the second guide groove 61.

[0055] Specifically, since the second guide groove 61 on the lifting handle 6 is inclined relative to the sliding direction of the fixed tooth 51 and the second guide block 511 on the fixed tooth 51 is accommodated in the second guide groove 61, the fixed tooth 51 can be moved when the lifting handle 6 is pulled.

[0056] In this embodiment, by converting the axial sliding of the fixing tooth 51 into the movement of the lifting handle 6, the user only needs to apply a simple lifting action to smoothly complete the unlocking or locking operation of the fixing tooth 51 through the mechanical mechanism between the second guide groove 61 and the second guide block 511, avoiding the inconvenience and space limitations caused by directly manually turning the locking member 32.

[0057] like Figures 1-4 As shown, based on the above embodiment, a second elastic element (not shown in the figure) is also included. One end of the second elastic element abuts against the lifting handle 6, and the other end of the second elastic element abuts against the cushion 5.

[0058] In this embodiment, when the lifting handle 6 is pulled, the second elastic element is compressed, and the fixing tooth 51 separates from the lifting groove 22. At this time, the backrest 5 can be pulled at will to change its height. When the backrest 5 reaches the appropriate height, simply release the lifting handle 6, and the fixing tooth 51 will engage with the lifting groove 22 under the action of the second elastic element. Under the action of the second elastic element, the locking action can be completed automatically without manually pushing the lifting handle 6 back or applying additional operations.

[0059] like Figures 1-4 As shown, based on the above embodiment, both the adjustment handle 4 and the base 1 are provided with reinforcing ribs 14.

[0060] In this embodiment, the adjustment handle 4 and the base 1 are provided with structurally optimized reinforcing ribs 14, which greatly reduces the overall weight of the adjustment handle 4 and the base 1 while ensuring overall strength and durability, making the user's rotation action more effortless and smooth.
